Removing a Fan Module from an EX4300 Switch
The fan module in EX4300 switches is a hot-removable and hot-insertable field-replaceable unit (FRU) installed in the rear panel of the switch: You can remove and replace it without powering off the switch or disrupting switch functions.
Ensure that you have the following parts and tools available:
Phillips (+) screwdriver, number 2
An antistatic bag or an antistatic mat
A replacement fan module
The fan module slots are at the left side of the rear panel on 24-port and 48-port switches, and at the right side on 32-port switches. Figure 1 shows how to remove a fan module from 24- port or 48-port switches except EX4300-48MP and EX4300-48MP-S switches. The procedure is the same for 32-port switches. Figure 2 shows how to remove a fan module from EX4300-48MP and EX4300-48MP-S switches.
- Place the antistatic bag or the antistatic mat on a flat, stable surface.
- Loosen the captive screws on the front faceplate of the
fan module by using your fingers. If you are unable to loosen the
captive screws by using your fingers, use the screwdriver.
To prevent injury, do not touch the fan with your hands or any tools as you slide the fan module out of the chassis—the fan might still be running.
- Grasp the handle on the fan module and pull it firmly to slide the fan module out of the chassis.
- Place the fan module in the antistatic bag or on the antistatic mat placed on a flat, stable surface.
- Install the replacement fan.
- Tighten the captive screws on the faceplate of the fan module by using your fingers. If you are unable to tighten the captive screws by using your fingers, use the screwdriver.
Both the fan modules must be installed and operational for optimal functioning of the switch.
